/**
* Checks if editor selection should be changed because of click at the given point at gutter and proceeds if necessary.
* <p/>
* The main idea is that selection can be changed during left mouse clicks with hold <code>Shift</code> button and we want
* to distinguish that situation from <code>'close line numbers gutter'</code> action (activated by <code>'Shift+click'</code>
* on gutter area).
* The main idea is that selection can be changed during left mouse clicks on the gutter line numbers area with hold
* <code>Shift</code> button. The selection should be adjusted if necessary.
*
* @param e event for mouse click on gutter area
* @return <code>true</code> if editor's selection is changed because of the click; <code>false</code> otherwise
